More than anything else, the one single play from the Grbac era that screams no leadership was the play at the end of the playoff game against Denver. One play to keep the game winning drive going. The one where the headset in his helmet malfunctioned, and he went into full meltdown right there in front of a national TV audience. Pissed right down his leg while slapping the side of his helmet indicating he couldn't hear the coaches call. I still can not see a franchise QB doing that. A Manning, Brady, Favre, Montana, or any other QB would have know what to do in that situation instead of peeing down his leg like Grbac did.
Cassel... I see him being able to make a call and run the correct play under those circumstances without having someone make it for him. Weather or not he could make the play work?
But he did look better last week than any other game this season. Can he continue to build on that this week against a tougher Steeler defense? If so, then I think maybe he could be a franchise QB. If we take a couple of steps backwards this week, then I would still have to question if he is the correct choice to lead us into the future.
